The UK need to react quicker to e.g. floods and COVID 19 response. Having a social tax separate to income and corporation tax would help to build and provide a fund to assist and finance recovery from unplanned disasters better and faster without it being "wasted" in other areas. It would also offer a buffer and allow other government functions to operate without having funding pulled so much or the country going into more debt.
